Read the passage below and answer the questions based on
understanding of the passage. (Question Nos. 46 – 50) :

Communication
media have evolved along with technological transformations and progress. Man’s
inborn need to communicate led to the first medium for the global transmission
of information – the printing press, followed by the rotary printing press. But
the need for information has always been in continuous growth, so that
inventions such as telegraph had to be adopted for information transmission by
waves. Indeed, the radio was one of the society’s great technological and
democratizing advances. But there is no doubt that television has succeeded in
making McLuhan’s idea of the existence of a television tribe a reality. Large
companies, which control access to information by methods that are close to
being a monopoly, wage fierce battles in order to control mass media,
especially television.

The
“fourth power’ collects, disseminates and preserves a great quantity of information.
This information is thematically diverse and exists in a wide variety of
formats and media. In order to control such an important business asset, almost
all television broadcasters have set a documentation service that is
responsible for satisfying journalists’ information needs and for the
maintenance of the firm’s intellectual and cultural heritage.

Documentation
centres are just the visible aspects of a great
documentation web involving different classes of documents, varied media and
the diverse requirements of end users. The computerization of documentation
structures is a reality that is sustained by a constant exchange of information
between documentalists and communication scientists,
aimed at enabling the preservation of information and access to this
information by means of a standard set of parameters.

The
thematic descriptors must describe, viewed and referred content in the
audiovisual documents with precision. Thematic identification has a special
importance since it is the usual method for accessing information. For these
fields, different television companies use different proprietary ad hoe tools,
with thesauri being the formula employed to control vocabulary. There have also
been experiments aimed at developing effective tools based on faceted
classifications. The

fact
that audio-visual information has to be analysed from
two different perspectives in order to understand the challenges offered by
this kind of document should be considered. The visual and the sonorous sometimes
are complementary, and consequently must be studied and analysed
by the information manager. Sound and visual tracks do often collaborate to
create a joint informative message, but it is also very common the case where
both contribute to create quite different meanings.
